Measure
Use bills, room temperatures, humidity and the EPC to identify the real weak points.
Spend less energy staying warm in winter and cool in summer. Start with the fabric, airflow and controls—then size equipment around the improved home.

Four stages designed to reduce wasted spend and avoid treating symptoms.
Use bills, room temperatures, humidity and the EPC to identify the real weak points.
Tune schedules, thermostats, shading and ventilation before buying new equipment.
Address unintended draughts without blocking air bricks, extractors or combustion ventilation.
Prioritise continuous, correctly installed fabric measures and treat damp causes first.

A practical fabric-first sequence for deciding what to do first.
